 Not really.

 And still:
 {{{

 Nothing to be done
 An error ocurred, return value: 22.
 Collected errors:
 Failed to download tinyproxy. Perhaps you need to run 'ipkg update'?
 }}}
 I also tried with -t /mnt/tmp - so the issue is not missing RAM or space.

 bifferos, here it also affects my own repository on the apache in the
 local network.
 So I tried as bmilde did:
 {{{
 root at OpenWrt:~# mv /usr/lib/ipkg/status /mnt/
 root at OpenWrt:~# ipkg install tinyproxy
 Installing tinyproxy (1.6.3-1) to root...
 Downloading http://192.168.1.2/~tom/openwrt/./tinyproxy_1.6.3-1_mipsel.ipk
 Configuring tinyproxy
 Done.
 }}}

 Very interesting.
 What's the issue?
